The resulting set of elements from jQuery's selectors and methods is always represented by a jQuery object. Such a jQuery object is very easy to work with when we want to actually do something with the things that we find on a page. We can easily bind events to these objects and add slick effects to them, as well as chain multiple modifications or effects together.
Note that jQuery objects are different from regular DOM elements or node lists, and as such do not necessarily provide the same methods and properties for some tasks. In the final part of this chapter, we will look at ways to directly access the DOM elements that are collected within a jQuery object.
